Hi all.. :)
I wanna ask you about IDisposable. What if my class doesn''t have constructor when we want to implement IDisposable interface ? Is there any problem ? May you explain me ?? :) Thanks

推荐答案

如果您未明确包含构造函数，则C#将自动提供不带参数的默认构造函数. (请参见使用构造函数 [

If you don''t explicitly include a constructor C# will automatically provide a default constructor that takes no arguments. (See Using Constructors[^])

There is no problem implementing IDisposable on a class that contains only the default constructor.

It is also possible to explicitly define the default constructor and mark it as private (preventing instantiation from outside of the class itself). Even in this case it is still perfectly OK to implement the IDisposable interface, but you will have to be aware of where you are instantiating your class from and who is responsible for calling Dispose(). You may find you have to call it manually rather than using the usual ''using'' statement.
